Pressure Reducing Valves
Pneumatic Operated - PCV-100 SERIES
Product description:
Globe Type, Single Seated, Top & Bottom Guided, Single Spring & Diaphragm Actuated, Pneumatic / Motorized Operated Pressure Reducing Valve
Design:
- PCV-100 series Pneumatic / Motorized operated pressure reducing valve is high in demand where accurate down stream high pressure control with high flow is required.
- Top & Bottom guided design for high stability & accurate pressure control
- Cage guided design is offered for highpressure requirement.
Features:
- Top & Bottom guiding provides maximum support to the plug for it’s stability and eliminates the side thrust effect of pressure drop across the plug.
- This valves are designed to control fluid flow at high pressure
- Up stream & Down stream pressure control for Air / Gas / Steam / Liquid.
- This design provides tight shutoff capability for such processes.
Application:
Bri-Con Pneumatic / Motorized operated pressure reducing valve can be used for many Industrial application where reducing high pressure of steam, gases and other fluids to be kept constant with high pressure & high flow.
